Crocus Continuous Flow Dryer
The Crocus Continuous ﬂow dryer is designed to dry
grain and similar free-ﬂowing products such as wheat,
barley, rape seed, maize and Soya beans. The dryer
is typically deployed in the grain and agricultural
industries etc..
Quality
The Crocus Continuous ﬂow dryer is manufactured
to industrial standards from 2-3 mm galvanised steel
plate. Its design ensures effective usage, minimal running and maintenance costs and a long lifetime.
Technical data
Matching your needs
The dryer column is manufactured in 5 standard
sizes: GS, GT, GM, GL, GXL.
The number of drying and cooling sections in the
column may be varied making it possible to adapt
capacity and reduction of water content to individual
drying and cooling needs and local conditions. Discharge regulation ensures that run through times can
be adjusted likewise.
All Crocus Continuous dryers can be supplied with
direct or indirect heat sources including natural gas
and diesel, with or without dust extraction.

The dried product is discharged via motor driven discharge rollers. Rate of discharge is controlled from
the switchboard using interval regulation.

Air is sucked from the air channels across the grain.
As a result a vacuum is created which minimises
heat loss and dust. The uniform passage of the grain
through the dryer ensures that every single grain is
affected from all directions and ensures a homogeneous drying.
Discharge regulation
1
Warm air
Each dryer section is equipped with a number of Vshaped air channels. These channels are narrowed
at one end, designed so that the product only comes
into contact with smooth surfaces and are staggered
in relation to each other ensuring a uniform distance
between the channels and an even product distribution throughout the dryer column.
The discharge trays under the rollers are equiped
with springs to prevent foreign bodies from damaging the rollers. The easily regulated active discharge
ensures a homogeneous passage through the dryer
and provides complete control of the drying process.
Complete control
The drying process is controlled and monitored from
a single control panel with a built-in safety cut-off
switch.
Level sensors may be placed in the pre-hopper in
order to ensure that the top dryer section remains
full during operation. The dryer section may also be
equipped with temperature sensors.
The control panel may be supplemented with control
of associated transport equipment.
